Not sure if this is about your relatives, but how many Bisi's could there be in the Pittsburgh area? From my limited Italian, it seems the family started a pasta company in the Pittsburgh area and Ralph was a son or grandson of the founder. http://portale.lombardinelmondo.org/naz ... ernestbisi
Secondo questa lettera, sembrerebbe che Ralph è stato il figliastro di Ernest, e che il cognome di Ralph era, in verità, Bonestolli.

Caption: Aunt Rete gave this list of names of her siblings to Paul bertram Maglione who typed it and sent it to tim DeFrange in 1978. with the exception of Pauley's poor spelling, this list is a reliable source to determine who was born a Bisi and who was born a Bonistalli.
